DISCUSSION OF DATAYield of Grass In the study of the data collected in this investigation, the yieldof grass naturally commands first attention. While the yield may haveno relation to the nutritive value of the grass, it is evident that anyincrease in yield means an increase in the total supply of food bearing upon this point is presented in Table 1. From this tableand derived tabulations and curves, not only the variations in yield maybe studied but the influences responsible for -9- Bearing in mind the different treatment cf the plots and the factthat the soil, variety and stand of grass were as nearly alike, in allcases, as it was possible to select, the influence of the following factorsupon the growth of pasture grass is present. (a) The age of the pasture season. (b) Tillage,(b) Manure. (d) Frequency of cutting grass. In order to arrive at any conclusion as to the influence of thesefactors upon pasture grass, it was necessary to assemble or calculate thedata from the experiment to a form convenient for study. Plot 1, theuntreated plot cut weekly, is the check plot of the whole experiment. Inthe study of the effect of age of the pasture season, the results fromthis plot alone are used as this one corresponds neares* to the pastureunder average farm conditions. The difference in the results from thecheck plot and the corresponding disced plot (Plot 3 cut w
